Global deal on aviation emissions puts EU scheme under pressure

The 191 members of the International Civil Aviation Organisation (ICAO) sealed a deal on Thursday (6 October) aimed at ensuring carbon neutral growth for the booming sector after 2020, calling into question the future of the EU’s existing scheme to reduce airlines emissions.

Air traffic is expected to double by 2035. In order to maintain the same level of CO2 emissions overall, the sector will rely on leaner engines consuming less fuel, re-adjusted air routes and the use of biofuels.

The ICAO General Assembly, held in Montreal, reached a landmark compromise to offset the remaining emissions beyond 2020 levels with projects that contribute to reducing CO2.

Commissioner for Transport, Violeta Bulc, said shortly after the news broke in Canada that she was “very happy” with the adoption of the global market-based measure to offset emissions.

Europe sees ICAO deal to curb aviation emissions within reach

Transport Commissioner Violeta Bulc said she was “cautiously optimistic” about reaching an agreement to limit CO2 gases emitted by passenger jets starting in 2021, following meetings at the International Civil Aviation Organisation (ICAO) conference in Montreal this week.

Bulc had initially said she was not “in love” with the agreement, partly because the scheme will be mandatory only after 2027, instead of 2021. Besides, there were no details about the mechanism itself. This task was left to technical groups that will have to design the instrument over the next three years.

Still, the EU Transport Commissioner welcomed that around 65 countries, including all EU member states, China and the US, will join the market-based mechanism as from 2021.

She said the EU “will remain vigilant that it [the GMBM] lives up to our expectations and is well implemented”.

And she underlined that the review to take place every three years (the first one in 2024) will help to keep the political ambition of the deal on track.

Some countries including Russia, India, South Africa, Saudi Arabia, Brazil, Chile or the Philippines will not join the scheme during the voluntary phase (2021-2027).

First step

Environmental organisations warned that the “hard-fought political compromise” reached in Montreal is a “first step”.

They worried about the lack of clear provisions to ensure the transparency of the technical process for finalising the market-based mechanism, the key pillar to limit CO2 growth by 2035.

According to Bulc, the deal on the table will serve to offset 83% of emissions above 2020 levels between 2021 and 2035. Environmental organisations, for their part, put the figure at 75%.

“Work must begin immediately to improve the deal, and Europe must go further with its own, more effective, measures,” said Andrew Murphy, a campaigner at the green NGO Transport and Environment (T&E).

For T&E, the EU should strengthen its own aviation Emission Trading Scheme (ETS), in order to fully achieve carbon neutral growth for the industry.

Future of ETS in question

The aviation ETS was received with scepticism by environmentalists when the scheme was first launched years ago. But they have changed their minds and now defend the scheme as a stronger response to aviation emissions than the offset mechanism negotiated at global level.

The ETS allocates a carbon budget to airlines based on historical emission levels and allows them to trade the surplus on the EU carbon market, providing an incentive to pollute less. Initially intended to cover all flights departing and landing from Europe, the EU decided to “stop the clock” on the scheme in 2012 because of widespread protest from third countries, including China and India, which threatened to boycott the scheme.

Since then, the scheme has applied only to intra-EU flights, to the disappointment of European airlines, which feel penalised against foreign competitors.

For NGOs, the agreement concluded in Montreal is so “weak” that Europe should apply the ETS to all flights again.

On the opposite corner, the largest European airlines want to dismantle the ETS as a whole.

“Following the ICAO agreement, there is now an opportunity to have a fresh look at environmental regulation in the European context and to review existing measures addressing CO2 emissions from aviation”, said Thomas Reynaert, Managing Director of Airlines for Europe (A4E), a trade organisation representing Air France-KLM, British Airways, Iberia, Lufthansa, EasyJet and Ryanair.

Following the ICAO agreement, the Commission now has to make tough decisions about the future of its ETS. One likely option is to permanently exclude third countries from the scheme. But some fear that, by doing so, the executive will also cripple the scheme for intra-European flights.

For now, the Commission is keeping its cards close to the chest.

Bulc could give a hint of her views next Wednesday, when she is expected to appear before the European Parliament’s committee on environment to explain the agreement reached at global level.

She can expect a tense exchange with MEPs, who recently expressed widespread dismay at the tentative ICAO deal.

MEPs shocked by ‘secretive’ ICAO plan to cut aviation emissions

A six-year delay, exemptions for poor nations, and a gradual phase-in system for participating countries are all being considered as part of talks to curb aviation pollution at the International Civil Aviation Organisation (ICAO), MEPs discovered at a hearing in Parliament today (1 September).

Bas Eickhout, a Dutch MEP from the Green faction in Parliament, has already stressed that “there is no need to review the ETS system in place”.

Following the exchange of views in Parliament, Bulc will consult with fellow commissioner Miguel Arias Cañete, responsible for climate and energy, on how to proceed with the ETS.

A first proposal is expected by the end of the year.


European Commissioner for Transport Violeta Bulc said, "This unprecedented agreement opens a new chapter in international aviation, where sustainability finally becomes part of the way we fly. Europe has been continuously advocating global and coordinated action to address the growth of aviation emissions which was otherwise set to reach 300% by 2050. Today European solidarity and perseverance has delivered."

Transport & Environment aviation director Bill Hemmings commented: “Today is not mission accomplished for ICAO, Europe or industry. The world needs more than voluntary agreements. Without robust environmental safeguards the offsets won’t cut emissions, leaving us with a deal that amounts to little more than adding the price of a cup of coffee to a ticket.”

Thomas Reynaert, Managing Director of Airlines for Europe (A4E) stated: “This fair, uniform and global system is the most effective way to complement the continuous efforts of the aviation industry to develop cleaner aircraft, switch to low-carbon fuels and operate more efficiently in order to keep CO2 emissions at 2020 levels”


The airline sector, like the maritime sector, has its own UN agency, the International Civil Aviation Organisation (ICAO), which is responsible for organising the reduction of its CO2 emissions. ICAO was tasked by the Kyoto Protocol with addressing emissions from the sector.

It has been difficult to reach a global agreement. In 2012, with no deal having been made, the EU included aviation emissions in its Emissions Trading Scheme. The decision sparked a backlash from the industry and foreign countries, like China and India who refused to comply with the scheme and threatened the EU with commercial retaliation measures.

The EU’s temporary halt to the ETS was intended to allow time for the ICAO to devise a global alternative. But in the meantime, international airlines which bitterly attacked the cap and trade scheme at every turn will be exempted from it, while intra-European airlines, which had supported it, will not.

As a whole, the aviation industry continues to fiercely resist market-based measures as anything more than a stopgap, advocating instead a formula of technological and operational improvements - plus the wider use of biofuels - to reduce emissions.

Airlines make up 2% of worldwide CO2 emissions. But the doubling of passengers every 15 years has made it a growing source of greenhouse gases. Due to the strong link between the sector and fossil fuels, reducing its CO2 emission is a challenge. The problem of electricity storage rules out its use in the air, which thus leaves airline manufacturers, which have promised to stabilise their CO2 emissions by 2020, with few options.
